Fireflies
We humans tend to divide insects into two camps. There are those we don’t like (Earwigs, I’m looking at you!), and those we do, with no better example than Fireflies. I captured this lone Firefly’s flash at my home in central PEI recently and thought it’s time we took a closer look at these interesting insects! Fireflies are beetles, not flies, and not all have ‘fire’ – many species are daytime-fliers that use pheromones, rather than light, to communicate. The night-flying,

Ox-eye Daisy
This week, we’re looking at a couple of edible non-native wildflowers that are in season right now. On Monday, it was Tufted Vetch; today we have Ox-eye Daisy (Leucanthemum vulgare). Most people are familiar with Ox-eye Daisy’s distinctive white petals (ray flowers) surrounding the golden-yellow centre (disk flowers). This cheerful-looking plant can be found across the Island, pushing up through cracks in sidewalks, growing among the stone landscaping of highway dividers, l

Common Comfrey
There are some PEI plants that, when I find them, suggest there was once a homestead nearby. Wild Apples and abandoned Lilacs are two examples, but so too is Common Comfrey (Symphytum officinale). Comfrey is native to Europe and parts of Asia and was brought to North America as a medicinal and ornamental plant in the 1600s. This plant’s name attests to its long history of medicinal use: Symphytum is from ancient Greek words meaning ‘unite’ and ‘a plant’, while officinale wa

Red-mouth Bolete
I love meeting a new-to-me mushroom, and so was quite happy when I found these among my favourite patch of King Boletes (aka Porcini) last week. Meet the aptly named Red-mouth Bolete (Neoboletus subvelutipes). Followers of this page will know that mushrooms with spongy pores rather than gills, folds, or teeth under the cap are boletes. (Not all boletes have spongy pores, but mushrooms that do are boletes. And if you haven’t been following this page, you can get caught up on

Starry False Solomon's Seal
When we think about wildflowers, coastal areas often get overlooked in favour of fields, forests, and roadsides. But that means missing some of PEI’s loveliest native plants, including Starry False Solomon’s Seal (Maianthemum stellatum). Starry False Solomon’s Seal is a relative of Wild Lily-of-the-Valley, which I introduced you to earlier this spring. If you guessed these plants are members of the Lily Family (Liliaceae), you’d be sensible, but wrong! The genus Maianthemum

Alternate-leaved Dogwood
It’s great to see landscaping with native plants becoming mainstream. Many nurseries now carry at least some native species and seed mixes, while PEI’s Rural Beautification Society has added a Native Planting & Biodiversity category to its popular annual competition. The Island has many common, native plants that make beautiful additions to backyard gardens. One example: Alternate-leaved Dogwood (Cornus alternifolia). PEI has four native Dogwoods, which are all easy to spot

Is this edible?
This year’s damp weather may not be popular with everyone, but it has been great for mushrooms! The abundance of fruiting fungi has brought out a crop of social media posts asking about edibility. Here are some tips to help you ask the right questions and get reliable answers! I love encouraging people to try wild plants and fungi, but I cringe every time someone asks “is this edible?” That should never be your first question; instead, start with “what is this, and how can I

Common Lilac
Some PEI plants are inextricably linked with people – not only in how the species arrived here, but also in their ongoing social and cultural value. I can think of no better example than the Common Lilac (Syringa vulgaris). Lilacs are not native to North America but were among the earliest flowers brought by European settlers. Considering the harsh conditions and limited space on ships crossing the North Atlantic in the 17th century – not to mention the utilitarian worldvie

Tartarian Honeysuckle
Public awareness of invasive species is high now, but that hasn’t always been the case. In the 1800s, if a foreign plant was edible, medicinal, or pretty, it was brought to North America without much thought. As a result, we are now dealing with dozens of problematic species, including invasive Honeysuckles. Tartarian Honeysuckle (Lonicera tartarica) was introduced to North America from Asia in the 1840s as an ornamental garden shrub. The same traits that make it attractive

Virginia Ctenucha
Welcome to Insect Appreciation Days, celebrated from June 8 – 13th annually, thanks to the Entomological Society of Canada. And what better insect to profile than PEI’s most commonly-reported moth, the Virginia Ctenucha (Ctenucha virginica)! First, what’s up with that name? Ctenucha (ten-OOO-sha) comes from a Greek word for ‘comb’, and refers to the feathery, comb-like antennae of the male moths. (The individual shown here is a female, with more wiry, less feathery antennae

Ruby-throated Hummingbirds
With their tiny size, fearless personalities, and amazing agility, Hummingbirds capture our imaginations in a way few other birds can. PEI has only one species – the Ruby-throated Hummingbird – and their time with us is as short as an Island summer: from roughly Mother’s Day to Labour Day. Hummingbirds are creatures of extremes. They’re our smallest birds by far, weighing just a few grams (or about as much as a Canadian nickel); it would take more than 1,000 Ruby-throats to

Eelgrass
There’s one PEI plant that most people are very familiar with, but few have seen growing in its natural habitat: Eelgrass (Zostera marina). This is how most of us know Eelgrass: washed up along the shore. Eelgrass actually grows in extensive beds offshore as well as in our bays and estuaries, and – despite what you may think – it’s a true flowering plant and not a seaweed. Eelgrass has roots, stems, leaves, flowers, and vascular tissue (structures that move water and nutr

Black Knot Fungus
This is a great time of year to spot a PEI fungust that's best known as a disease of Cherry trees: Black Knot ( Apiosporina morbosa ). Black Knot fungus forms distinctive, black galls on stems and branches of our native Pin Cherry and Chokecherry, as well as ornamental Cherries and Plums. While it’s unattractive, reduces fruit production, and may kill the infected branch, Black Knot doesn’t usually kill the entire tree unless the infection is very severe. Within those black

Flying Squirrels
One of my favourite PEI animals is seldom seen despite being fairly common: the Northern Flying Squirrel ( Glaucomys sabrinus ), shown here in a photo by Ron Serres (used with permission). Flying Squirrels are beautiful, large-eyed, soft-furred animals, with a flap of skin (called a ‘patagium’) running from wrists to ankles on each side. That flap allows them to glide 50 metres or more between trees in the forest and has been copied by the wingsuits used by some BASE jumpe

Lung Lichen
You may think there’s no old growth forest or wilderness on PEI, but that’s not true. We have amazing ancient and wild spaces if you know where to look and can recognize the signs. Lung Lichen ( Lobaria pulmonaria ) is one of those signs. A lichen is a unique creature: usually, it’s a combination of a fungus and an alga or cyanobacterium functioning as one organism. But Lung Lichen is one PEI’s few tripartite lichens: it includes a fungus, a green alga, and a cyanobacter

Snake Tracks
We’ve reached that time of year when my weekly posts switch from plants and fungi to wildlife tracks and sign. Here’s a nice reminder that not all tracks are made by feet! The dry summer weather made for great tracking conditions along PEI’s unpaved roads. This site near Mount Stewart had all sorts of footprints from insects, birds, and mammals, along with the unmistakable undulating trail of a snake. The size of the snake track told me which of our three species was the culp

Parula Warbler
Earlier this year, my youngest (and largest) dog was cornered on the deck by something that was clearly very scary. I rushed to rescue him and immediately saw the fearsome creature: this lovely Northern Parula Warbler ( Setophaga americana ). ( No birds were harmed in the taking of this photo ). The Northern Parula is one of about 20 species of migratory warblers that breed on PEI. I’m no birder, but the Parula Warbler’s distinctive call is one of the few I recognize: a fast

Cocklebur
If I had to design vegetation for a movie set on an alien planet, I’d take inspiration from this PEI plant: the odd-looking Rough Cocklebur ( Xanthium strumarium ). Cocklebur gets its name from spine-covered fruit (burs) that look a bit like Burdocks but have two distinctive beaks at the end (inset photo). Like Burdock ( Arctium minus ), Cocklebur’s Velcro-like fruits are distributed by hitch-hiking on animals, including humans. Those burs also float, allowing them to be r
